everyone take a look at (in my opinion) the worst game of the franchise:star wars Episode III revenge of the sith. the one level in the jedi hall of records were you commit genocide to librarians,jedi,and guards. now one of the type of guards in this level hold their lightsabers backwards their move selection contians moves that make holding their light saber backwards work i dont remember specifics but they had a redesigned fighting style that apparently worked so my point is dont you think that the creators TFU would have addapted to the charicters stance and made holding the lightsaber behind their back workable?

it seems obvious to me that you wouldnt get shot just standing OR maybe their is an automatic thing in the game where the charicter moves to block any fire directed twards him/her
